== Introduction ==

'''Lactuca sativa var. asparagina''', commonly known as '''Celtuce''' or '''stem lettuce''', is a variety of lettuce belonging to the family '''Asteraceae'''. It is a cool-season annual crop, primarily valued for its edible stem, which is often used in Asian cuisine. Celtuce is a hybrid that combines characteristics of lettuce and celery, offering a unique flavor profile reminiscent of both vegetables<ref>https://nutrition-and-you.com/celtuce.html</ref>.

== Characteristics ==

* '''Physical Characteristics''': Celtuce is distinguished by its long, firm, and succulent stems, which can grow up to 12-14 inches in length and 3-5 cm in diameter. The stems have a crisp texture and are often used raw or cooked in various dishes<ref>https://nutrition-and-you.com/celtuce.html</ref><ref>https://growables.org/informationVeg/documents/Celtuce.pdf</ref>. The leaves are bitter and tender, but less commonly consumed compared to the stems<ref>https://nutrition-and-you.com/celtuce.html</ref>.
* '''Growing Conditions''': Celtuce thrives in cool weather conditions, similar to other lettuce varieties. It prefers well-drained, moist soil with a pH between 6 and 6.7. It is typically planted in the fall, winter, or early spring, spaced about 8 inches apart<ref>https://growables.org/informationVeg/documents/Celtuce.pdf</ref>. Celtuce is hardy and can tolerate a wide range of temperatures, making it adaptable to different climates<ref>https://nutrition-and-you.com/celtuce.html</ref>.
* '''Lifecycle''': As an annual crop, Celtuce completes its lifecycle within a year. It is propagated by seeds and can be harvested when the stems reach the desired size before bolting occurs<ref>https://growables.org/informationVeg/documents/Celtuce.pdf</ref>.

== Why is this crop useful for space? ==

Celtuce could be beneficial for space cultivation due to several reasons:

# '''Nutritional Value''': Celtuce is rich in vitamins A and C, folates, and fiber, making it a nutritious addition to space diets<ref>https://nutrition-and-you.com/celtuce.html</ref>. These nutrients are crucial for maintaining health and preventing diseases in astronauts.
# '''Adaptability''': Its ability to tolerate a wide range of temperatures and grow in cool conditions could make it suitable for controlled environments like those found in space habitats<ref>https://nutrition-and-you.com/celtuce.html</ref>.
# '''Low Maintenance''': Celtuce is relatively easy to grow and maintain, which is advantageous in space where resources are limited and manual labor is minimized<ref>https://growables.org/informationVeg/documents/Celtuce.pdf</ref>.
# '''Space Efficiency''': Celtuce grows upright, which could optimize space usage in hydroponic or aeroponic systems often used in space agriculture.

== History of Cultivation in Space ==

There is no specific information available on the cultivation of Celtuce in space. However, lettuce varieties have been grown in space as part of experiments to develop sustainable food systems for long-duration missions. For example, NASA’s Veggie experiment on the International Space Station successfully grew lettuce, demonstrating the feasibility of growing leafy greens in microgravity. While Celtuce has not been specifically mentioned in these experiments, its characteristics make it a potential candidate for future space agriculture projects.
